I tried to do a pano (just for testing purposes) with my Merlin and a 300mm lens.

I tried to import it via wizard to APG250b2 and the result was very strange. (pict 1+2)Then I retried it with APG209. Although it was way slower, it has a very good result, as I had expected (pict 3-5)Is this an issue of the importfilter? Any other ideas?
